Getting ready to fly again. PSA: I will wear a mask the entire time in the airport & during boarding (highest risk times). Once we are at high altitude, I will assess the sounds of those around me. ACH are high so the key is to make sure those close to you are not sick. (1/3) If I feel "safe", I will remove my mask to eat/drink but I will keep it on the rest of the trip. So far, this has worked as I have not gotten COVID-19 yet even with travel. It is all a calculated risk and each person needs to decide knowing people are traveling while sick. (2/3)

I'm just re-read @WHO's recent report. As motivation, they state up front: ".....during the coronavirus disease (COVID-19) pandemic, the terms ‘airborne’, ‘airborne transmission’ and ‘aerosol transmission’ were used in different ways by stakeholders in different" (1/4) "scientific disciplines, which may have contributed to misleading information and confusion about how pathogens are transmitted in human populations."
My question which has not been addressed: (2/4)

Oh @WHO-adding more confusion, not less. Why remove "aerosols" which means those particles that remain suspended in air (vs droplets that drop quickly) and can become inhaled?? My head hurts after reading this convoluted mess. (1/2)

Question for @who and those who remained to help on this report (I stepped away after seeing the unhelpful path it was going)--do you really believe "infectious respiratory particle" clarifies the main pathway to infection for COVID-19 and other respiratory particles??? (2/2).

Trying to understand breakdowns in communication during the pandemic. We tried to write a publication with Saskia Popescu and Angie Rasmussen. They backed out when I refused to eliminate the word "airborne". Here are their exact words: "We believed that the goal of this" (1/) project was to harmonize terminology across disciplines so that future communications could be clear and unified. However, we disagree that the word “airborne” should be part of this consensus nomenclature. While the word “airborne” has a broad definition (2/)

Twitter was an incredible place to connect people globally to help get out the word on #COVIDIsAirborne. I met so many amazing people as a result. Great things happened based on these connections. My main goal has always been helping people understand how to....(1/10) protect themselves when public health failed by denying airborne transmission was occurring. As I said on 6/1/20 in my interview with @DrLaPook , this is a fixable problem IF we acknowledge SARS-CoV-2 is airborne. Why not? SARS-1 was airborne. Precautionary principle? (2/)

This is an example of where CONTEXT should never be ignored. Note that his email to Dr. Fauci has TWO parts: 1)"Is this news" regarding a recent article on the potential for airborne? & 2) What should we be telling people about visiting the hospital if they are feeling sick? (1/)

Note that his question "What is the right message?" is in the middle of his second message (the focus of briefing the next day)--not #1. The fact is @DrLaPook was the FIRST chief medical correspondent on a major TV network to go against what public officials were saying. (2/)

Email I just sent to @CDCgov director after seeing their abysmal report on masking...

Hello,

I have spent the last few years helping people understand how to protect against the airborne nature of SARS-2. The pandemic should and could have ended long ago.  (1/) Seeing CDC's latest article stating that surgical masks are as good as N95's (for an aerosol!) has made me question the motivation of CDC.  We drink 2L of water per day. We filter water to remove pathogens. We breathe 70,000 L of air per day--but we do not filter it. (2/)

Things are really not OK in the water or the air at Imperial Beach. State of emergency has been declared. Remember, you can pick the water you drink (or swim in) and the food you eat, but you cannot pick the air you breathe!



(1/4)nbcsandiego.com/news/local/san… This is a serious environmental issue that shows you cannot hide waterborne pollution. Let's not forget these waterborne pollutants and pathogens can become aerosolized (and airborne) in the Imperial Beach region which exposes many more people.

(2/4)

Today was the pinnacle in terms of witnessing the impact of COVID-19 denial for me. I sat in my student's exam and only 1 other person had a mask. People looked at me like I was crazy. The good news is that the ventilation was good based on CO2 levels when I walked in. (1/4)

The bad news was when one of my colleagues got up and shut the door (see above). You can see the effect of what happened when they chose to do so. No one else seemed to care even though they were now in a petri dish of airborne pathogens. Massive shared air. (2/4)

My first year student Maile Heyer (co-advised with Lisa Zeigler) giving her first year seminar today @Scripps_Ocean. She talked about sampling the aerosolization of microbes from the ocean and potential health impacts. Feeling proud...it was an excellent presentation. @UCSanDiego Really important slide showing the motivation for her research...

Excellent article. Informative, clear, direct. One of the best of the pandemic.

Great job @jvipondmd @sameo416 @Mark_Ungrin -- thank you!! A few highlights below in thread (there are /many/ more in the article which is well worth a read)! (1/)

scientificamerican.com/article/masks-… .....they represent a well-understood engineered solution, with decades of widespread and successful use behind them. Demands to reject this evidence reflect a failure to recognize and respect interdisciplinary expertise that has undercut the global pandemic response. (2/)

.@theNASEM “Iceberg” provides the critical framework around which we reconcile our perceptions and understanding of #sexualharassment. The egregious cases make the news but we’re here to address that COMPLICIT OCEAN that keeps this ENTIRE ICEBERG afloat. See polls below (1/3). There are 14 examples of more hidden biases/harassments--how many have you experienced as a woman? (2/3)

This misinformation is being propagated largely due to a journalist @Slate who wrote an article with the title below indicating there is "not strong evidence masks protect against COVID" which is outright lie. This is a result of improper spin by the media. (1/2) The reporter directly states that the people she is quoting "wrongly" believe the review shows masks don't work, yet the title of her article ends up being "There's still not strong evidence that masks protect against COVID". There is serious ethical problem here. @Slate (2/2)

Based on my feedback from many members of the public, the reason most who choose not to comply and wear a good fitting respiratory (KN95, N95, KF94) protection is because of the poor messaging. So many times, I have watched a person with no mask wipe down their grocery cart (1/4)

and then put hand sanitizer on their hands. This is the main message they are getting as evidenced by all of the bottles of hand sanitizer you see in public spaces w/ no visible filtration systems. Given how effective filtration devices are at removing all airborne viruses, (2/4)

My concern: When you walk into a school or business, what do you see? Filters or bottles of hand sanitizer? No contest. The fact that after 3 years we still see people scrambling to scrub surfaces while ignoring scrubbing the air suggests most people are still confused. (1/)

As a scientist and engineer, I care about the science too but I am deeply committed to improving communication to the public at a level that saves lives. Does it mean I don't think people should study surface transmission? No. (2/)

Two ways to respond to those calling out poor messaging by a top public health official. 1.Block & chastise them. 2. Call them out, and then publicly apologize, acknowledging their frustration. #2 restored my faith that people can still be civilized adults on Twitter.(1/3) Many of us joined the blocked by Joe Allen club on 10/22/22. For the record, I never wished harm on anyone. The night before this official tested +, I expressed frustration in thread that has now reached over 1M. I'm clearly not the only one. #CovidIsntOver #COVIDIsAirborne (2/)

Someone asked me why I feel one reason for the slow admission of #COVIDIsAirborne is due to a COI. Answer: Because the chair of the infection control committee for the @WHO has stake in a company that puts hand washing machines on the walls of hospitals (John Conly). (1/2) This is the same man who says N95's are bad for you because you get acne. So when @WHO finally acknowledged #COVIDisAirborne on 12/23/21 with an asterisk next to it--saying IPC did not approve--why did no one launch a major investigation into this crime against humanity? (2/2)

My response to @CDCDirector.

After nearly 3 years, I am beyond stunned at your recent Tweet...talks about washing hands and doesn't say a word about masks or cleaning indoor air. This has led me (as a member of four scientific academies) (1/)

to write to you to beg you to please fix your message. COVID-19 is airborne. It is not on surfaces as CDC has reported (<1 in 10,000 chance of being infected from fomites). I am in complete disbelief after reading your tweet. (2/)
